Hi Jamie at 3.5k RPM have full boost(1.0bar),but spooling from around 2.6k-2.8k RPM
But now is fitted with VF34 which have similar characteristic spooling,but make more BHP(350-360bhp at 1.4-1.5bar)

for some reason it feels like theres something holding mine back as mine is on full chat at about 4000 which i dont think is right, i got a feeling it might be the ****e dumpvalve i have on but not shore

its a 02 wrx bugeye totally standard apart from a baileys dump valve which came with the car and have also read they are the worse dumpvalve too so am thinking of changing or going back to standard also have just put on a cat back exhaust but my cats are still in place its been boosting like this since ive had the car so the exhaust hasnt changed it

Hi Jamie get rid of Bailey DV and get Forge Recirc Valve or standard OE Recirc Valve.
For best you will try book your car for RR(Rolling Road),where you will when car start spooling and where is peak and etc.Cost for RR is around £45-£55.
This is best option for you,matey

Here is the Prodrive brochure which appears to have a standard WRX map on the graph also. I'd imagine your car should be similar (I think the ECU's changed, hence MY03 onwards quoted, but wouldn't have thought the basic map would be much or any different...).

Basically you should feel it really start to pull from 3000rpm. As stated above you really need to get rid of that DV as your likely loosing power with it on.

Hope that helps a bit.
